[HTML imports]: Removing imports

I've already opened a bug that import removal is not clear to me
(https://www.w3.org/Bugs/Public/show_bug.cgi?id=24003), but there
is more...

So in one way or another imports are cached per master documents
so if another link refers to the same import in the import tree it
does not have to be reloaded. Question is, when to remove the import
from the cache (let's call it import manager).

One version is to release import documents when the master document
is released. Another would be to wait until all the link elements
that refers to it are released. But maybe it should be released the
moment the last referring link element is detached from the
tree... this way users could force re-try import loading. Because
right now, if import loading failed, there is no way to re-try it.
Any thoughts?
